FRAMING-UP DEVICE FOR MOTION-PICTURE MACHINES.

Specification of Letters Patent.

- Application filed October 5, 1914. Serial No. 865,130.

ticularly'to the features constituting a framing-up provision,- that is, the relative adjustability of the film, focal and lens tubes, for properly spacing the film pictures one from the other in relation to the projecting area of the lens. I

I have designed a machine capable of alternate use for taking, printing and projecting moving pictures, and one of the essential features enabling such a. varied use, comprises a unitary lens board organization, interchangeable relative to a light-box or camerabox, and having provision for removing the lens support and framing-up the 'light exposure aperture for printing.

It is desirable to have a lens-board and film feed frame and guide, relatively fixed, and to provide elements-adjustable on the lens-board for framing-up In the type of machine shown, employing an axially alined lens-tube and focal-tube carrying the film exposure aperture, it is desirable to provide means for unitarily adjusting said lens and focal tubes. To this end, I provide a lens-board formed with an aperture enlarged relative to the lens area and adjustably supporting "the lens on the board within such aperture. The focal tube or other instrulnentality carrying the film.

- exposure aperture is also unitarily adjusttrolling unit of a projecting machine. Fig.

2 is a. plan section on line 4:4, Fig. 1. Fig.

3 is a front elevation thereof. Fig.4- is a similar view with the lens-board removed.

The unit shown consists of a front-board 1, a base-board 2, and a lining plate 3, to which the side frames 4, 5,=supporting the film feeding mechanism are secured. The

lens-board 6 is detachably secured within a f recess in the front-board 1, and contains a vertically adjustable lens-plate 7, support- Pamnted Dec. 21, 1915.

ing the lens-tube 8. A vertically adjustable focal tube-plate 9 is mounted in the frontboard 1. near the lining plate 3 and carries a focal tube 10 which projects rearwardly through an elongated aperture in theliningplate and terminates with a framing plate 11. The guide plate 12 is of elongated-double 8 formation, having an intermediate straight portion provided with an elongated opening 18, in which the framing plate 11 is guided. The film is guided during its.

travel past the focal plane by channel strips 1 l 14: on either side of the opening 13.

Any form of film feeding mechanism may J be employed in connection with my improved frammg device, the form shown 0011- sistmg of a constantly driven feed roller 15 above and below the focal plane with an intermittently driven roller 16 intermediate the focal plane and lower feed roller.

In ordinary projecting machines it is permissible to place a light shutter in front journaled in the lining plate 3 and carries a pinion 21 which meshes with the teeth 22 of a double-faced gear loosely journaled on a stud 24. The beveled teeth 25 form continuations of the teeth and mesh with the beveled gear 26 secured to and rotated by,

the power shaft 27. hen projecting it is necessary to properly frame the pictures with the framing-plate 11, by vertical adjustment thereof, also the lens-plate 7 must axial alinement of the focal-tube and lens tube.

, For adjusting both plates 7 and 9 in unison, provide a handle 23, (see Figs. 3 and pivoted on. an upright 29, secured to the lining-plate 3, (see Fig. 1), said handle carri'es' a clevis 30, having hook ends 31 and 32, the hook 31 engaging into an aperture in the upper end of the focal tube plate't), and the hook 32' engaging into an aperture in the upper end of the lens tube plate 7.

The lens-board unit comprises the members 1, 3, 6, 7 and 9, carrying the tubesS and 10. The lens tube support- 6 is readily detachable, enabling the focal tube 10 to be independently adjusted for framing-up incidental to printing work.

While the framing-up device is principally'used in projecting pictures, it is to be noted that I desire to use the same unit, for taking and printing pictures. The framingup device is light-proof as an entirety. The lens is adjustable for framing-up in a lightproof lens or camera-board, and the focal tube is light-proof except as to light admitted throughthe lens. When the unit is used for taking film pictures, the camera-box incloses the lens-board, and when the lens cap is taken off, the only light to which the film is exposed is through the lens and focal tubes. llithout this focal tube, or light-proof framing-up provision, the li ht would diverge around the film frame and touch exposed portions of the film within the camera-box.

So, when the lens tube is removed for print-' ing, the light is exposed only to the surface to be printed, as the focal tube excludes light from entering in rear of the film frame. So also iii-projecting pictures, the rays from the light box are all directed outwardly through thefocal and lens tubes defining the picture an a. and cannot spread or diverge between the film. and the inner end of the lens tube. So a light-proof lens-board and framing-up device, are of the utmost practical value, in a unit intended for interchangeably taking, printing and projecting pictures.

Having d scribed my invention, I claim 1. Ina device of the class described, an apertured lens-board and film guide, a lens tube and focal-tube axially alined and adjustably supported in relation to said apertures. the inner end of the focal-tube having a framing-plate adjacent the film guide aperture, and means for unitarily adjusting the said tubes on the lens-board.
